IMPROVEMENT IN TAKE-UP FOR THREAD IN SEWING-MAGHINES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN FANNING, of Brooklyn, in the county of Kings, and State 0f New York, have invented, made, and applied to use, a certain new and useful Improvement in Thread-Take Up for Sewing Machines; and I do hereby declare the following tobe a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein I Figure 1 is an elevation of the needle-bar, and parts that carry and move the same, with my improved take-up, with the-parts in the position they occupy when the needle is out of the cloth, and

Figure 2 is a similar view, .with the needle at the extreme downward movement.

Similar marks of reference denote the same parts.

In sewing-machines that form either a' single or a double-loop stitch, it is very important that the loop of needle or upper thread be drawn fully up when the upper or perforating-needle completes its downward move ment at the next penetration thereof, in order that the first loop may be entirely out of the way of the. lower needle or looper, so as to avoid the risk of the same taking'two loops and breaking the thread.

Diificultie s have heretofore been experienced in accomplishing this object, and, at the same time, allowing suflicient slack thread to form the loop as the needle rises.

The nature of my said invention consists in an eye near the end of the lever that moves the needle-bar, in combination with an eye upon the standing head or arm of. the sewing-machine, and above the said lever, so that the eye on the said lever, lll moving down with the needle-bar and needle, is at a greater'distance from the stationary eye, and hence draws upon the thread as the needle descends, sufliciently to take up the loop of the needle-thread'left from the previousstitch below the cloth.

In the drawing a is the'bed of the sewing-machine. t v I '6 is the fixed arm, carrying at its end the needle-bar a, with the perforating eye-pointed needle 01. e is the lever to the needle-bar, on' the fulcrumf, and actuated in any usual malnneng is the spool of thread, and any desired tension-apparatus may be employed. 7a is the eye on the arm 6, which is va fixture, but may be adjusted, if desired, so as to be located at the proper point, to act in conjunction with the eye 2', that is upon and moveswith the lever e, to draw up the previous loop of needle-thread. 4 v 1 o I It will be evident that the thread, shown by red lines, will be slaekened when in the position of fig. 1,.hut when the distance between it and iis increased by the descent of the. needle-bar and lever e, the thread will be drawn upon in proportion to the position of the eye it on the arm 6, and the consequent angle at which the thread stands to the eye z, when the needle has penetrated the cloth, as in fig. '2. V

The thread passes through the eye is, at the upper end of the needle-liar, where there may be'a spring to allow for inequalities, and thencesaidthread passes to the needle.

What I claim, and desire to secure by Letters Patent, is-- t The eye it upon the arm 6, in combination with the eye inear the end of the lever e that moves thecnee'dl e bar, so arranged nsto draw upon and tighten. the thread between the eye It and the guide It on the needle-bar, as the needle descends, for the purposes set forth.
